BooleanExpression

@webda/ql

Class: BooleanExpression

Defined in: packages/ql/src/query.ts:777

Constant expression from a TRUE / FALSE literal

Constants are folded while the tree is built (see foldLogical), so this only remains when the whole filter is FALSE; a filter that is entirely TRUE is the match-everything AndExpression([]).
